Cross is designed to process an intelligent extend/trim to crossed lines and curves, only by picking two points to define a rectangle window in the graph screen. The program will filter the objects across the window area: only lines or curves on active processing layer will be selected. The lines or curves will be erased if they totally lie within the window area.

Cross is a shareware and locked by RegisterShell for VLDCL in 30-days-trial mode. The products can run in trial mode with full functions for 30 days after the first calling date. The only inconvenience is that the RegisterShell will appear each time invoking the products. After the expiration date, the products will be locked permanently and only registering it can activate it again. The registration will disable the compulsory appearance of RegisterShell.
